TESSAN JA-B02A Tower Extension Lead, 5 m, 8 AC Outlets and 5 USB Ports

The TESSAN JA-B02A tower extension lead combines eight AC outlets with five USB ports and a 5-metre cable. Its four individual switches and compact tower layout suit desks or rooms where several devices need power, while USB charging claims vary between sections of the listing.

At a glance

Eight AC outlets and five USB ports are claimed to let the tower power or charge multiple devices in one place.
The 5-metre lead offers more reach to a distant socket than a short desk extension.
Four individual switches control AC power by side. The listing says USB ports remain powered independently of these switches.
Four-sided tower styling and four non-slip mats are intended to keep the unit compact and steady on a desk.

What to know before buying

Listing details to confirm

USB charging information is inconsistent: one section specifies 2.4A per USB-A port and 3A per USB-C port, while another gives 12W maximum for USB-A and 15W maximum for USB-C. The listing also claims surge protection without giving a rating. Confirm the charging limits and protection details if they matter to your setup. USB ports are described as always powered, even when AC switches are off.

Who is it for?

A good fit for

Home or office desk setups that need several AC outlets and USB charging in one compact tower.
Buyers who need a 5-metre lead to reach a socket farther from their devices.
Users who want separate switches for groups of mains-powered equipment.

Less suited to

Buyers who need clearly documented USB charging output or a stated surge-protection rating before purchasing.
Setups where USB charging must be switched off using the individual AC switches.

The supplied evidence contains aggregate ratings but no written customer feedback, so it does not establish specific praised features or reported problems. Ratings are mostly five-star, with a smaller one-star share, indicating generally favourable but not uniform responses. That broad signal cannot confirm the claimed outlet count, USB output or surge protection, which buyers should assess from the listing details.
